I have a Lenova ThinkPad Windows laptop on Win 10 Enterprise, Build 19045. After updating from 19.3 to 19.4, the program began crashing whenever I clicked on a text box.

I tested with different documents with the same results. I tried a few of the "usual" fixes for crashes (including removing the prefs folder and exporting to IDML) with no success, so I downgraded to 19.3. Downgrading fixed the problem, so there appears to be a compatibility problem with my system.
