Hi Andy!
I haven't tested UP3 but it seems that many stock classes have been modified in depth. Regarding the Minimap, at some time we were talking with Zuti about it and he merged my radar and other stuff into his MDS classes. I don't know how is the situation now. Have you seen the UP3 minimap, does it have something extra?
Regarding the Combo, I think that in the FMB we probably have hundreds of differences, mainly in the FMB, because as far as I know he doesn't modify anything in the GUI classes. But my GUI classes (QMB and the extra functions of the Briefing) need a couple of changes in the FMB to work properly. Eventhough I don't clearly understand why do you receive the error when launching the mission, because there isn't much work performed at that instance.
I have updated the MissionProCombo, now it has many bugs fixed, some improvements, specially in the QMB, but I think that will be as incompatible as the previous one with Zuti MDS:
The change log includes basically these:
QMB: Fixed many subtle bugs. Now Regiments don't change when you select a different map, they are perfectly read from the Arming screen, etc. Now we have the chance of having Briefings for QMB missions!!! That was a serious missing from my point of view. New Dialogs appear if you select a map that is not installed in your game, etc. Bail Out can be supressed from QMB missions too, only you and your flight can jump, not the rest.
FMB: I moved the Map submenu formerly present in File Main Menu because everytime you wanted to Open / Save or whatever, the autoexpandable Map List covered all the screen, making it very painful. I'm about to implement an On-The-Fly switch to the Map Builder mode. Now the reading of the Mission Properties is ammended and we don't have anymore the weird problems of the original FMB.
MissionPro: solved some bugs. Now the transfer of the Mission to the FMB is perfect, including the Properties and a reference to the original file (previously you only were editing a copy of it). Now it reads all the changes you generate to the User Profile when you go to the Arming screen and applies it to your current mission, etc.
If you try it, please tell me about any bug or improvement you consider could be made.
Regards,
Pablo
