i don't know if this is already reported, but fasmw sometimes hang when i save files.
recently i lost about 20 hours of work when a file was going to be saved, it seems like the program had enough time to wipe out everything in the file, but not save the new info before it hang..

i always press Ctrl+S almost per minute :p

Bad tht you lost your work, posible solutions:

Autosave only save each X time in a file with the same name called name.backup when you hit save button, it will save the actuall work in the file.asm that you are working, if hang, then in the reopen can watch for backups if they exist and restore them.

In the OK exit of the program will delete the abcup files that was in use (Only need bacups if they are necesary, ie a crash or a hang).

hmm.. ok, i will try to download the newest version.
and right now i am doing manual backups, before each save..
