I have a c# windows forms with nothing crazy going on in it, just regular business things like creating quotes and orders and taking payments and things like that using a hosted Sql DB.

My problem is that when employees run it for more than a few hours without closing it, the memory is collecting without letting go and makes the computer perform terribly. If I press Ctl-Alt-Del and look at processes in the Task Manager, the memory usage climbs and climbs over a few hours until its over 150,000 K, sometimes over 300,000 K. My firefox, for comparison, usually runs at about 40-60,000 K.

I can't figure out whats going on here with this program. It is killing performance every day. Does anybody know whats going on or how I can fix it?
