LiveCode Forums

Would you believe it!! After deleting these plugins, all the unexpected behaviours stopped. Now everything is as should. Thanks to everyone who helped.

Thanks for everyone's interest. I would run LC from the app not a stack. Once LC is running with this rogue window, I opened any stack then invoked "Close and Remove from Memory", that cleared the rogue window. Also every button I clicked would come up with a beep and refuse to do anything. But then...

Here is a screen shot: maybe I'm stupid! Whatever image I use this refuses it. Whether it is pict or img or whatever.
Can someone please advise as to the best one?
BTW, when I move the mouse over the window and type ⌘M, nothing!!

On launching LiveCode have a strange window appearing. About 10cm deep and very, very long without any buttons to get rid of it. Any ideas what this is and/or how to get rid of it?
