DSS freezes upon generating a Star Mask and changing the extension to FITS

Not what it does for me:

How did you get it to do that?

I thought I did the exact same thing you took a screenshot of, but wasn't able to get it to replicate exactly. What did happen while I was trying to replicate the problem was I got an error saying "Encountered an improper argument" upon changing the "Save as type:" field to FITS. DSS locks up after and I have to end the task in Task Manager.

Updated the issue title to reflect the error unless I can manage to reproduce the missing extension. Although I'm wondering if they're somehow related...

I did try to repro the issue but unless you can give me exact steps to re-create, I can’t fix. The default behaviour fills the fileid is Starmak.tif or Starmask.fit Maybe the fact that you removed the extension caused the issue? D.

I'm sure I've seen this (just the missing extension, not the lock-up) too, but I didn't realise what had happened until some time afterwards and didn't have time to go back and investigate further.

After restarting DSS what I did this most recent time was:

1. Open DSS
2. Open picture file (via Processing Menu -> "Open picture file...")
3. Create a Star Mask (via Processing Menu -> "Create a Star Mask...")
4. Proceed with default star mask settings
5. On the save file dialogue I didn't change the file name or navigate to a different folder, just clicked the "Save as type:" dropdown and changed TIFF to FITS. Then the error dialogue appeared.

This one I'm able to replicate repeatedly.
