Error when middle-clicking "new tab" tab

[quant]

but I'm afraid ... the AV's are not history ... but I'm sure the most troublesome are over

Just opened my db after installing new fix. It has 2 tabs from previous session. Middle click (instead of left click) on "new tab" just next to tabs causes AV error ... and happens every time in ANY db that has more that one tab, so hopefully will be fixed ;-)

I don't know ... in general, is this a programming problem of errors not being caught properly? It shouldn't just throw AV error at user ...
