Bug 93380 [DnD] 100% CPU usage when dragging files in the navigator or package explorer
Reported: 2005-05-01 22:12:38 | Status: resolved fixed

Version: 3.1.0 Build id: I20050419-1200 When i drag and drop a file inside the package explorer or navigator views the CPU says at 100% (or 50% when hyperthreading is enabled). Since the CPU usage doesn't go above 50% my guess is that all of the processing time is spent in the event thread (windows doesn't seem to let the virtual CPU on the event thread, hence the 50% number). I do not see this massive use of CPU when dragging an external file into the navigator or when dragging a file out of the navigator. Dragging views/editor is also ok. I will try to get some thread dumps either tonight or tomorrow.
