i had the same problem, it does it when you upgrade the ide. try ctrl+alt+del you should find your program running in the background, and sucking up your cpu resources. everytime you try to compile your program, a new instance of it will be created, it'll slow your pc down dramatically.
try totally uninstalling dbp,
then install it off the cd,
then install patch 5.1
then install the first ide update,
then install the second ide update.
^^ that worked for me anywho.
