I'm by no means a computer geek but here are some things I do.
Uninstall the game and delete all SH4 folders, I use an eraser program.
If you just delete files be sure to empty the recycle bin before installing anything. Don't forget the SH4 folder in "My Documents"

When you reinstall put the game in a different folder ex. old one SH4, new Silent Hunter. Don't use Program Files folder.
I have the game on my E drive and that is the only program on that drive.
Before I reinstall I defrag the drive. Also defrag the drive from time to time. Also after you install the game don't play it but do a full shutdown/restart.

Use fresh copies of all mods not ones used before.
Make sure you delete the Mods folder from JSGME before uninstalling anything else. Delete the mods one at a time not all at once.
I think it was Bubblehead that had a problem with this, about drove him crazy or at least crazier than before.

Install the stock game and run it, ok than add the mods one at a time and run, may find what is causing the problem.

I use to get those bugs before but for some reason they went away by themselves after a time but I didn't have as much a problem as you seem to be having. It would happen only once in a while and I think a new patrol fixed it.

One other thing I never do is Alt/Tab out of the game, I save and quit if I leave the game for short time, Its easier to restart than go through what you're doing now. Alt/tab is a death sentence for me. I use to be able to do it every once in a while but since I put a second install on can't do it now????

Hope all this helps, it's the pits to have these kinds of problems.
