[LH846] Beta 11: Application hangs during conversion of script formats

I load a test file, containing script pages.
I change the format of a script element
A dialogue box pops up offering to convert all script elements to the new format (I think that is what it said).
I click ok.
The application hangs. I can only close it by going into Task Manager and ending the process.

Can we get a small project with the script formats causing the hanging, simeva? You can upload it here or email to tiho at literatureandlatte.com. Thanks in advance!
