I don't know if this is a bug, let's call this a missing feature
You could choose Custom Colors in ConvertAll.
- Options --> Set background color --> Add to Custom Colors or
- Options --> Set text color --> Add to Custom Colors
These colors are saved in the Registry:
Your launcher doesn't save and restore this key, it only deletes the key. So the Custom Colors are lost at next launch.
PS: Well folks, don't post the same in my FreeMat Portable thread, Dev Test 3 has the same missing feature too. Edit: Feature added in Dev Test 4
PPS: Another small thing for the next release: Legal Copyright: PortableApps.com and contributors
