DNGConverter multiple About screens - minor bug

[#1]

Not sure if this is the place for reporting bugs... this is for DNGConverter 9.12 on Windows 10.

I noticed that if you click the About button multiple times you get multiple About panels.

Click About, move the main windows, click About again.

Certainly just cosmetic but should be low-hanging fruit for the dev team.
