LiveCode crashes a lot

[cavenewt]

MacBook Pro 16gb RAM, Mac OS 10.8.4, LC Commercial 6.1.1-rc-2 Build 2007. I'm learning to save after every operation because it crashes so frequently. The only stack I've been working on is the summerschool app.

The only plugins added are MobGui, ICMover and ICResTool. I did do the MobGUI Recover which did not help.

I'm updating to the latest version, LC 6.1.1-rc-3, (just released) to see if that helps.

Here's the relevant part of my crash log, in case someone knows how to interpret it better than I do:

Nope, still crashes. The relevant Thread 0 in the crash log is identical to the one I posted earlier.

All I was doing was closing a script window on which I had already pressed the Apply button.

I had the same problem until I stopped using the new Project Browser. I think there's a crasher bug in there. Try closing it and see if that helps.

The Application Browser is the older tool that does much of the same things. I use that instead.

I'm using OSX 10.8.4 also and find LC to be buggy. I normally crash when I put something in a script that is not part of the LC syntax (which is why I keep looking for a resource on proper use of the syntax).

The Application Browser is the older tool that does much of the same things. I use that instead.

I also have a lot of problems with the Project Browser. I know you can click-drag the layers to reorder them, but sometimes the mouse will grab a layer for no reason and not let go. Also the icons don't always update. I'm going to give this a shot.

Thanks for the tip.

I will try the App Browser, of whose existence I was blissfuly ignorant. I had been in the habit of keeping the Project Browser open most of the time.

[cavenewt]

Been working all day with the App Browser rather than the Project Browser, and nary a crash. I hope this is something that can be fixed, as the PB is more convenient to use.

Thanks for filing that report.

Engine-wise, I think the only thing new the Project Browser uses is the thumbnail generation, made possible by the "at size" option added to the "export" command.

My guess is that if any of you have a need to make thumbnail and put the new "at size" option under stress testing, we may be able to hone in the recipe.

There's enough complexity in something like the Project Browser that my hunch may just be a goose chase. But since the issue is a crash rather than a script error, I'd start with relevant recent engine changes.

Can you think of any other engine changes that may come into play there besides "at size"?

Richard...

Where is 'at size' documented ?... or to put another way... in which 'release notes' has it been mentioned as I don't see it in the dictionary

Hi everyone

If you can come up with a recipe, for any problems with the Project Browser please post here or file a bug report and we will investigate.

If you think it might be the thumbnails causing the problem you can turn these off in the preferences and see if that makes a difference.

Thanks

See the Dictionary entry for the "export snapshot command.

I don't know if this will help give RunRev a clue, but when the Project Browser starts to display weird, random behaviors (like layer views disappearing, or getting cropped off, or the mouse not letting go of a layer and starts dragging it up and down the list) I find that if I close the Project Browser and re-open a new view it usually starts working again. At least for a while.

I have turned off the thumbnail display for the Project Browser in Preferences and will report back.

I'm using the Project Browser with the thumbnails turned on. I'm finding that when I click on the thumbnail or the label in the layer, the Project Browser behaves strangely. If I click on the name of the object everything is fine.

For example (see attached): If I click on the label "Graphic:" a lot of odd things happen, but if I click on the name "background" it is fine.

Edit: I should add that the strangeness happens *mostly* when I'm trying to select multiple layers via command+click.

Something worth mentioning here - the thread opened with cavenewt saying that they were using LC Commercial 6.1.1-rc-2. Please be aware that rc releases are not stable, shipping releases. They are test releases (rc stands for Release Candidate). If you experience issues with an rc release you might try reverting to the last stable build, which will have no letters after its name - 6.1.0. We would also appreciate a bug report, here:

I hope this helps,
