09:09:37:223 Are you sure to close MuLab Project and quit? => Quit without Save
09:09:37:232 Gonna shutdown ASIO engine
09:09:38:954 A serious error has occured. => OK
09:09:38:964 Error Region[24]

NOTE: ML is registered, in the log it says "MuLab FREE 6.4.18 32 bit" instead.

NOTE: This is minor, but I think ML under Windows should respond to the standard ALT-F4 shortcut to close the program.

If you need more info, just asks.

Thank you.

Do you mean you got that same red error alert?
Note that that red error alert pops up when there is a catched crash. Although that red error alert looks the same in such case, the reason for the crash can have very different reasons.

Yes it was the same alert, thats me just assuming it was the same reason as it involved the keyboard, my bad

The VMK crash bug is fixed in the next version. It was a low level bug that could possibly have caused other occasional crashes too. Difficult to say whether that bug was also related to the scrollbar preference/minimize crash, reported recently. I don't think so, but atoh it could be. Anyway, this bug fix that will generally further increase stability. That next test version will be available soon.

Thank you for the superquick bug-squashing.
