Win7 64-bit... RC4...
Load FITS image, activate Fast Rotation from Process Explorer, rotate image 90* clockwise, drag instance triangle onto image. Move bottom border of window downwards (to accommodate image now in portrait format - longer vertically) with mouse.
I get to about 90% full window size vertically, then this error dialog pops up:
PCL Win32 System Exception
At address 000000013FEC97D6 with exception code C0000005:
Access Violation: invalid memory read operation at address 000000000FA64000
When I press the "OK" button (no choice), PI becomes unstable: whenever I move the mouse over the image and then rightwards past the original border, I get multiple added right side borders offset by about 200-300 pixels each. The extra borders disappear if I move the mouse off the image, then back over it. Sometimes, the mouse acts like I've pressed the left button to drag a border, even thought I'm just moving it over the image. The mouse pointer itself disappears when hovering over the image, and I can't close the image by clicking on the "X" in the top right corner, because the mouse pointer doesn't seem to go there (because its not visible, its hard to tell).
I CAN close the image using File | Close or Close All. If I try to reopen the same image, the image window is just a grey box containing no data. Again the mouse behaves quite erratically.
The only way to get back control over PI is to shut it down and restart. There is no error dialog or crash when you shutdown PI.
I tried this sequence with two different images, and got the same behavior both ways. Fortunately, no damage appears to occur to the image(s) already loaded during this episode, although I didn't try to save any unsaved changes before closing them.
Can anyone else reproduce this behavior?
