Good afternoon, This is possibly a windows only bug, definitely of comparatively low importance - but for the sake of completeness here we go. I've searched http://bugs.R-project.org/ etc., but can find no mention. For RGui.exe, the CPU usage goes to 100% for certain dialog boxes for the duration that the dialog box is visible, e.g. * check CPU usage is low * On the RGui.exe menu chose File / Change dir... * the CPU usage goes to 100% * hit OK * the CPU usage goes back down again
What is the bug here? I'd guess it's not R using the cpu, rather some other process hooked to the dialog, but even if it really is R, why is this a bug?
Maybe R is sitting in a loop consuming all the resources of the system?
It's a SHBrowseForFolder call, with a callback. If there's a bug, it looks to me as though it's in Windows. Duncan Murdoch
