I've run into a bug that seems to happen when looking at very long lines of code, I've included the file that makes fasmW crash. Have a try and see if anyone else has this problem too.

Does it crash on loading this file? What system are you using? I was not able to reproduce the crash.

Please make sure you've got the latest update of fasmw - this version is constant development and is updated frequently.

Well, I just found out where my post went!
I'm using FasmW version 1.54, the latest release that I know of.
I'm using a windows xp home edition SP1, on a intel celeron 2.7ghz processor. It does not crash when loading, just crashes when I use the horizontal scroll bar to scroll through the source code. I tried it again, and seems to crash only when I use the scroll wheel on my mouse. This could be a windows bug, who knows.

It was indeed a bug in whell scrolling - I just forgot to finish that routine. Thanks for the report, it's fixed now.

Thanks, Good Work.
