I have this problem where if I press the LMB and RMB at the same time, mouse movements don't register until I release one of them. Does anyone else get this?

Rosewill RM-1600L

Why do you need to press them both at the same time anyway? I don't think it matters that much

Doesn't do that for me. I have a Logitech.

Maybe you should just switch the configuration for key inputs. It may just be your mouse because when I play New Vegas it works fine for me.

First of all, get yourself a Grenade Rifle. >:l SMGs are pathetic and inaccurate.

Secondly, Logitech. My wife uses an M305 travel mouse, and it works wonderfully. Optical, lightweight, micro-wireless transponder, and it runs off of a single AA battery, which can easily be a rechargeable L-i. Altogether, a twin charger, two batteries, and the mouse should burn thirty caps ou-.... Erm, thirty bucks outta your pocket. They're small and comfortable. Unlike mine. :3

An alternative, for the time being, could be to simply change the key config. Put Zoom on, say, space bar, and jump on your right key. Because honestly, how often do you jump? >:l

Bill's on it's way. I'll have a courier ship it out to you.

Apparently NV will not let me assign actions to mouse buttons. I'll have to do it in the INI file.

If it were such a common issue as to be possible to ask if anyone else has it, they wouldn't be on the market. This case is certainly rare at best. I do have an USB mouse, yet I'm using a PS/2 adapter with it. Why use up free USB ports for a component that another port exclusively specializes in?

Dude Jared, Get yourself a Anti-Material Rifle......
I recently started having this problem, but it stopped after a while. I'm wondering if the game causes this now...

For me the best 2 mice i have used.
My RF wacom mouse/pen
Microsoft mouse (Still hasen't ever been attached to a windows pc)

Anyways I have only ever heard of that issues with buttons on wireless keyboards. 3 key pres smaxs dosen't work on games
