My dictionary crashes every time, i read it has been fixed, but i can't make it work.

I have deleted preferences files, reinstalled, but still the same. Is there any solution for this? it's really annoying.

Windows & LC 8.01, but its the same with 8.1DP2.

Win is not my preferred OS [I use Win only to test and not to develop stacks.]

But I tested just now and I have no problems on Win7 with the dictionary.
There are problems here on Win10 with LC 8.1.0-dp2:
The Guides tab shows a blank page, the API tab works.

You could use until the next update of 8.1.0-dp2 (it's still in alpha state):
http://livecode.com/resources/

You'll find there links to online Dictionary(API), Guides, Lessons, Courses and Samples.

LC 8.1 dictionary still crashes on windows 7, i have deleted appdata\roaming\runrev\preferences files, but nothing changed.

Any solution for this? it's really annoying.
