Yes, but I don't think that it is due to my modifications as it was working like a charm until a couple of weeks ago. Then I was not able to use it due to the wchar_t problem (it was crashing when loading a document), and now that I can use it again (thanks to Georg) it crashes when scrolling. So I cannot exactly say at which point the bug appeared. Note that Qt3 works ok and that I am not able to set "Cursor follows scrollbar" (I get "E2BIG There is not sufficient room at *outbuf."). I seem to remember that this setting was crucial(?) Rather, I think that it may be due to some nasty difference between MSVC and GCC. I'll try building Qt4 on *nix and test it there. > I cannot reproduce the crash. This hints to some difference between compilers, as there are crashes occurring with MSVC that I cannot reproduce with GCC. > Could you post a document that shows the > problem? No need to post one, every document that can be scrolled triggers the crash for me :( -- Enrico
