Column ordering in import dialog box in v.2.1.3

[actopossum]

Description:
There seems to be an issue with ordering of columns in the import data dialog box that is triggered when using the arrows to move rows up/down.

To Reproduce
When trying to import a data matrix file (.txt for e.g) in Perseus v.2.1.3, I move the expression/ms intensity columns from the left to the right. If I try to use the up/down arrows on the right of the box to change the order of columns, it will cause the ordering to change but then it keeps moving and doesn't respond appropriately. It eventually crashes the program and the window closes without an error message.

Expected behavior
It used to just move and reorder the columns as expected.
