This is pretty minor, but a little strange.
When I save an image as a TIFF, in the TIFF Options dialog box, I cannot enter spaces into any of the text boxes on the right side of the box. The space bar is ignored when I'm typing. All other characters, including tabs, can be typed.
If I cut and paste text, spaces can be entered in the fields. It appears to be only when typing.
I'm running PixInsight Core 01.07.05.0779 Starbuck (x86_64) on Windows 7 64 bit.
