Hello Drewsky, back in May I had reported a AV with using SyntaxStyles. I do not know if what you are experiencing is the same as what I had experienced. But, I would suggest that you look at my post about it: https://support.tmssoftware.com/t/and-another-issue-with-scripter-v1-23-and-newer/14378
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.
