I can't reproduce the issue on the Windows64 client. You might have to give more of an example.
I am able to buy commodities from a city, take them out the hold and into my own inventory, put commodities into the hold from my inventory, change the gear of my crew, and nothing seems to crash my client or cause any issues.
Only minor issue I see was when changing the gear of my crew, the Unit Orders window didn't update the change of their gear correctly at first.
