I have now tried out SpritePad 3.52 and it works :-)
I was and still is using the W64 version.
I'm currently using both CharPad and and SpritePad via Wine + CrossOver on MacOS.
Unfortunately the latest version 3.50 of SpritePad won't start :-(
It just keeps printing:
00f8:fixme:unwind:RtlVirtualUnwind unknown unwind info version 0 at 000000000065FF50
- in the terminal windows until I kill it.
