Touch screen becoming less responsive?

[uofirob]

I've had my sprint touch for over a year now and recently the screen has become less responsive. Sometimes I have to tap the screen 4-5 times to get things to recognize and more often than not, it acts like I've clicked in the lower right hand corner. I don't know if this is from the manilla 2d rom I just installed (it was happening before the rom update) or from S2U2 1.42 (which was relatively new as well), or if it's just old age.

Has anyone else been having this problem as well?
