There is a Paratext user who is getting a crash when Keyman 10 is enabled. It looks like the crash is related to Text Service Framework.
I found instructions here for turning off integration:
The instructions are for Keyman 9 and I want to know if a modified version of the instruction would work for Keyman 10 on Windows 8.
I haven’t been able to reproduce the problem on my machine, so can’t test the instructions I would send.
