Squash -Em - Single User Description:

Desertware's Squash 'Em can help you keep track of those nasty bugs so none of them will slip through the cracks. The whole lifecycle of the bug is recorded and managed from the time it is entered into the system to when it has been validated and closed. The entire process is easily adaptable to your workflow.

Desertware's Squash 'Em can also track all your support calls throughout the whole life cycle. If a support call reveals a bug, it can be easily saved as a bug and assigned to development to be fixed.
