The app that I've been long developing now won't run after compiling with version 3.0.1! It halts in WebFormCreate, showing the following Debug info:
I hope that this makes sense to you without further info, but if you'd like to see the crash for yourself you can run it from the TWebDataGrid branch of my public GitHub project: GitHub - TPeterson94070/CW_EPG_Remote_PWA: Companion application to extend CW_EPG to remote clients · GitHub
Meanwhile, I guess I'll have to revert to 3.0.0.0. 
Can you try to set grid.FixedRows / grid.FixedCols at runtime to see if this helps?
Edit: Disregard below questions. I installed today's version 3.0.1.2 and it runs without throwing the subject error.
==================================
I'll have to re-install 3.0.1 to test.
2 questions before I do that:
The app has TWebStringGrids, TWebDBDataGrid, and 2 TWebDataGrids. To which should I add fixed row & column defs, all of them?
I believe that the crash occurs during Application.CreateForm(TCWRmainFrm, CWRmainFrm). So will fixed settings in runtime code have any effect?
We have released v3.0.1.2 yesterday. I suggest to check with this latest release.
