Forms 4.5 ROS -200 Error

I just joined this newsgroup last week so this question was probably already asked. While working on a VERY SIMPLE form I received a ROS -200 error when I tried to save my form (already was named, and had been saved a number of times). I also got this error quite frequently when taking the Forms 4.5 I course from ORACLE. There seemed to be no rhyme or reason, but I assumed the problem was with their hardware. Now the same thing happens on my machine while working on a completely different set of forms!

The ROS -200 error will not allow me to save my work and I cannot seem to fix the problem without exiting Windows.

Any information on this error would be greatly appreciated.

Thanks in advance!
