I am having issues with the latest version of TMS Scripter and RAD Studio Enterprise 10.4.2. I have attached the project. In the project please click on NEW button and try to edit source code of the project. I am getting access violations in SRCMEMO.PAS. Screenshot attached.
If I remove Memo.SyntaxStyles to nil then the problem goes away, but I do not get syntax highlighting. This used to work for years.
Even though there has not bee a Update release for TMS Scripter to fix the AV with SyntaxStyles that I had reported, and one other issue that I had previously reported. Wagner Landgraf did post a Diff file that fixes the AV that I was having with SyntaxStyles.
I would think that applying the changes shown in the Diff file may help to fix your problem.
