I've been looking some more at this bug you are both experiencing. From what I recall, George is seeing it in the Query Tool, whilst Mike is seeing it in the Edit Grid. I've seen another report for each from Ezequias and Harald.
Both tools share two important pieces of code:
1) ctlSqlGrid is our custom control that is based on wxGrid and is used to display the results. This code is primarily used to size rows/columns and extract data (ie. When exporting). Most of the real work is done by wxGrid which we've used since 1.0.
2) pgQueryThread. This is a class that is used to run a query asynchronously. It is this class that I fixed a couple of bugs in for beta 3 that had demonstrably caused crashes for me.
I suspect that the problem that remains is an issue in the wxWidgets code as pgQueryThread is fairly simple and there is little else to go wrong in it that I can spot. I did find a seemingly unrelated threading bug in wx right before beta 3 which I was forced to workaround, however I found today that wxWidgets 2.7.1 has been released, in which that bug appears to have been fixed.
So, before I go insane trying to track this down further, may I send you both an updated .exe built against wx2.7.1, in the hope that we've actually been seeing just one bug that's manifested itself in different ways?
Regards, Dave.
