I'm using 4.3.5 (Build 1463) on Win XP Professional.
At the moment I'm finding that if I try and delete a whole lot of saved sessions (imported from PuTTY) using the clean-up dialog... I get a message "Invalid access to memory" popup over and over again (not all at once, each one opens after the previous one has been closed)
Once the last popup has been closed, the saved sessions list clears.
(i.e. you don't see the sessions go one at a time, they all go together at the end)
I get up to one popup for each session.
i.e. I just tried importing 20 sessions & got 2 popups.
I then imported the same 20 sessions & tried again & got 19 popups.
Tools...->Import->(all are checked)->OK
Tools...->Clean Up...->Check "Stored sessions"->OK
*BANG* *BANG* *BANG*...
It doesn't happen if I've only imported a few sessions.
And it doesn't happen reliably - sometimes I can import 4 and delete them and I get it, other times I need to import 15-20 or more sessions.
I've tried different sessions to see if it's something in a particular session, and it doesn't seem to be.
Windows Task Manager says I have 2013196K of Physical Memory Available.
