I just got home from a long trip on Saturday, the 29th, and tried to boot up Studio to resume some work. A problem I quickly found, aside from the “Drive not found” error mentioned in another thread already, is that within a minute or two of loading a place, the camera movements and other mouse actions begin to lag out heavily.
After pulling up my Process Manager to see what was happening, just in case another progam might be eating into Studio’s processor space, I noticed that my hard disk’s megabytes per second were nearly maxing out per second. They quickly died down again, but they seem to be tied to mouse and camera movements in Studio. Any time I rotate or move the camera especially, the Mb per second maxes out instantly.
The only other detail I can find is that it seems to happen worse and more often if two or more places are open for editing at the same time, but is not necessarily required for the issue to happen.
