I'm running 4.17 atm and it seem stable with one exception.. It's a party crasher every time I open the format feature, however I found running 4.17 with 4.12's Dopus_Disk would correct that problem.

Last thing that is a pain atm is the fact that before I could run the config window in wb mode while having the main program on a cloned wb window. Now when using cloned window the config window ends on another custom window that uses the amiga rgb output not the CV output. Changing the setting to use wb window is ok for config purposes but then I lose the great wb/dopuw window switching possiblity. Dunno if it makes sence but it's irritating, might just have to find a settings for it in the new 4.17?
However I might have discoverred why it all was going down hill with my old DOpus... seem I've not been running 4.12 but a mix of 4.11 main program with the rest of 4.12's program files. That I found out after 4.17 installed and running 4.12 at that point posed no problems with copying so not sure if it's due to wrong main program (likely) or the new 4.17 files.
