Error Provider for validating in windows

Question

I m using error provider for validating the two textbox controls.
every thing works fine but the problem is that cursor is locked in textbox for which validation is fired.

i.e. suppose if the valdation for first text box is fired and error icon is dispalyed besides it. NOW if i want to click in second text box , i can't click in that, the cursor is locked in first textbox itself for which validation fired AND is locked there till i enter valid entry in first text box.

WHAT I WANT is to click in second text box even if validation remains fired for first text box and error icon showing for first text box.currently its not happening.

Can any one tell me how to do this ?
