Thanks for the Reply, I hope this helps. Calling textin_cb result in an heap or memory error when:
-The scrollbar is moved while textin_cb is called
-More then one page of text in the widget
(also happens without HG.e.ScrollEnd() Wink

Thank you

Still too little info. I do not even see when textin_cb is called....

A proper testcase is zipped package to demonstrate the rpoblem that compiles, most preferably on both Win32 and linux.

Anyway:

If you are using threads, you should use U++ threads, otherwise you will have memory leaks.

GUI can run in the main thread only.
