error message issue
Am facing an unusual problem.
I have designed a screen program and once i enter an invalid material in the screen , am showing an error message ...now the issue is once the error message is displayed am unable to change the material,if i try changing to valid material and press enter its directly exiting out of the screen.....,,After displaying the error message even am unable to debug the screen after entering valid material.
Hope the issue is clear. Pls sugges me with the alternatives.
