Can the pause functionality be modded or tweaked?
 

When having paused the game, it is not possible to do much of inventory shuffling and a most annoying thing is the impossibility of looking into several units inventory when having the game paused.

Turning pause on and off repeatedly becomes a chore in combat, is there perhaps any modding or tweaks that would change the way pause functionality works?

MOW is a really fun game but the pause functionality leaves much to be desired imo.

For those still unable to patch the game, I just found a work-around, and I'm here to share it with you! gorilla tag
Simply download izu-ftivcp.rar ("ftivcp" stands for "Freight Tycoon Inc. Vista Compatibility Patch"), and extract its content on the same place than you put the original non-working patch downloaded here, then double-click on "Patch.bat". It is basically just a simple "DOS" batch, which will do everything step by step, telling you everything in live. You can edit it if you wanna know more. It will extract the only usefull file from the original patch, search for your installation's folder (note to the game's developpers: this information is available in the registry, lol), rename the original file, and finally replace it by the patched one.

In some cases, software applications provide user settings or preferences that allow users to customize the behavior of certain features, including pause. Check the application's settings to see if there are options to tweak the pause functionality.

I'm guessing that some of the gameplaytweak modifications, such as tweaks galore, may modify this.

Semirandom research, on the other hand, allows for this.
