Been working on this for days with no relief in sight.

Mostly plegiarizing Alextp's demo_editor, I have built "my own" editor that I wish to specialize for another use.
I put the AtSynedit in a frame and placed the frame on a TPanel; this whole apparatus controlled via a TATTabs component.
The application will handle 'n' files and a TXMLPropStorage component provides persistency between executions.

I actually had most of this working once but I have broken it.

After recovering the data from the TXMLPropStorage component and building all the frames with AtSynEdit with an open file,...

This is the stack trace.

Code: Text  [Select][+][-]
  1. Program exception!
  2. Stacktrace:

I have run out of debugging expertise. I might have a better chance if I could get a stack trace of the events between the end of my initialize frames method and this and have had no luck in discovering that.

Thanks in advance.
Thank you for your help,

I got this narrowed down to whatever happens after  TTatTab click event is fired:

Code: Pascal  [Select][+][-]
  1. 04-2-21->13:15:36.713   BEGIN: TfrmLogFollower.TabCtrlTabClick 
  2. 04-2-21->13:15:36.728   ENDOF: TfrmLogFollower.TabCtrlTabClick 
  3. Program exception!
  4. Stacktrace:
  5.

I have not been able to fix this issue.

I reverted to a git commit prior to the advent of this issue and continued the search but it is a tedious process.
Thank you for your help,
