Actually it is all very strange. I am facing this issue in my office. When i switch to perl 5.8.3, the last entry widget in a multiple entry mega widget takes the input, rest all of them dont accept the input even if the cursor blinks in the entry boxes. Now when i switch to Perl 5.18.1, none of the entry boxes takes input, and i realized even Text box is not editable. But at my home where it all works well(on Ubuntu with different versions of Perl) Now i can't understand where the problem lies.
