[squeak-dev] Annoying bug: UndefinedObject(Object)>>doesNotUnderstand: #mimeTypes

Hi folks! I have a really annoying. I am in windows, using Pharo 10371 (Both: Pharo and PharoCore,) or sq3.10.2-7179dev09.03.1. I have the same problem with both of them.

VM: http://squeakvm.org/win32/release/SqueakVM-Win32-3.11.2-bin.zip

To reproduce:

1) Go to squeak
2) alt + tab to switch to another windows
3) alt + tab again to come back to squeak

At that moment, we you get the focus in Squeak you will get TWO DNU. They are the same.

I attach SqueakDebug.log

Thanks for the help.
