I've recently been having a most distressing problem with MC. It only happens when I run Full System Scans on Norton. If I happen to be streaming music from MC, which is usually the case, frequent dropouts will occur. By "frequent", I mean 2-5 or more times in just a single song. They last for about 5 to 10 seconds and then resume play until the next drop out. Pausing or stopping the scan immediately fixes the problem, but these are 2 operations that I would like to (and SHOULD) be able to perform at the same time. I really don't think this is an issue of having inadequate computing power: I have a Windows 7 64bit HPE 270f with Core i7 processor and 12 GB RAM. My conjecture is that the scan is accessing files on the hard drive that are allocated near the file that is playing. I recently installed a new PSU, added 4 GB RAM, and installed a 240 GB SSD. The drop outs seemed to start about the same time as these upgrades. Again, I don't think that it is related, but it might be worth mentioning. Has anyone else noted this or similar problems, and could anyone recommend a solution?
