Strange Win XP error messages

Recently my computer has begun producing odd messages whenever I drag files around. I have managed to trace it to whenever the ‘dragged’ files cross other files onscreen. I get two sequential boxes with a yellow exclamation mark sign, both titles

shelle~1

the first reading:

CShellExtension::XDropTarget::DragEnter

the second:

CShellExtension::XDropTarget::DragLeave()

This also happens if i right click, or delete using the keyboard.

Please help, since dragging files around each other is really infuriating.:mad:

This newsgroup article has a possible solution.

Thanks, that seems to have directed me to the problem, maybe i’ll learn not to install random demos in the future.
