What I did:
- opened Dir Hotlist configuration (Ctrl+D, Configure)
- copied an existing entry (using TC_StartMenu_DuplicateEntry.ahk)
- changed the title of that new entry
- changed 1 Byte of the entry's command line
- created a new line, entered title and command line (net.exe use ...)
- pressed Enter key so save

The newly added lines were saved correctly, though (seen after TC restart).

This is a known problem which has been fixed in TC 7.55 beta. It happens because TC tries to draw some lines in the dialog while the list has already been unloaded. The script is probably causing an additional refresh event.

Thanks.
The AV occured while closing the Hotlist window with Return key (when the script was long ago done with copying, but who knows), so your explanation seems to fit.

[ghisler(Author)]

I see - can you check withTC 7.55 final whether it fixes it, please?

[StatusQuo]

Well, I tried with both TC 7.50a and 7.55 - no errors.
But as this occurred only once (not reproducible) I can not say for sure, if it's fixed now, sorry (although I guess so).

For excact reproducing in TC 7.55 the script has to be updated (because of the changed control names), I tested with manually duplicating the line there...

[StatusQuo]

Sidenote:
TC 7.55 changes the used control names while running after some time of testing
(TButton1 gets TButton2 etc. in Dir Hotlist-editor).

On start: TButton1=Help ... TButton7=Add
=> Later: TButton2=Help ... TButton8=Add

In the second case TButton1 is titled "&>>" and hidden/not visible (according to window spy).

I'll update my script to handle this dynamic change ASAP...

TC 7.55, XP SP3 (home version this time)

I re-checked on several systems (including the original one, which got the error) => not reproducible.

As you already found and fixed something related - how about considering this as fixed?

OK thanks, otherwise please create a new bug report in the TC 7.55 bugs forum!
