There are actually two bugs here.
If you click on View, Topaz will spend a short period of time getting the
information for the report. The View button is not disabled during this time.
If you click on View before report is displayed, an error message is displayed.
The second bug occurs when the report is displayed, if you minimize the preview,
and click on View again. The second report is displayed. If you now close the
first preview, an error is displayed.
Depending on the state of the program at the time, you may experience problems
closing the preview or closing Topaz.
This is a small problem that will be corrected in a short period of time. As a
temporary solution, do not click on "View" while Topaz is busy creating the
report, and make sure to click on the "Close" button instead of the minimize
button when closing the preview.
