I installed the 64bit version of LL as Draftsight no longer supports 32 bit. However, the mouse does not move on the CAD screen properly - it seems to lag to the extent that it's unusable. This may just be a problem with Draftsight but if there is anything I can do in Linux Lite I'd appreciate it. I'm using a Lenovo X-130e laptop with a Logitech mouse. Thanks.
