BUG: Zoom text field not accept numbers when blank

[Travis]

I clicked on the Zoom tool in the lower right corner of the window to get the following dialog. I must have hit delete (to blank out the text field) and then tried typing a new percentage. I just get beeps and no typing.

Work around: use the up/down arrow to repopulate the text field and then the field accepts new values. Doesn't accept values when blank.

That is hard coded so it will only accept something between 6 and 500. So if you type "1" (in order to enter 100), it fails as "1" is invalid.

I'll change the code so it checks when you click OK instead.
