I've been getting this problem in Oblivion, Fo3, NV, Skyrim whenever I use Script Extender, what it basically is, is that whenever I'm playing with SE, my mouse sometimes refuses to register clicks and because of that, my attack rate is too slow and it's REALLY annoying, it's been haunting me for years, I haven't found any solution and now that I'm back playing NV, I want to ask here if anyone has encountered this problem and/or could help me find a fix. I've googled for years and I haven't met a single solution or even a problem with this case(Actually I found 1 but it was without any solution...) So yeah, I'd be really thankful if someone would help me fix this so I can play with SE. And yes, my computer is old and not good specs but I can run any game mentioned above on medium/low with good FPS, even if modded. Thanks! :)
