I'm having an issue where the tender screen becomes unresponsive. You cannot hit the cancel or OK button, X button to close the window, or use the arrow/number keys to make any changes in the tender window.
This is happening on machines running Win7 x64 and RMS 2.0.0126. We are using the Mercury/Retail Realm software for credit card processing. The issue typically occurs once you have entered the total or hit the + key to proceed with a CC/debit transaction, then the Mercury window pops up, and then the transaction is cancelled on the screen or on the IPAD, and it brings you back to an unresponsive tender window at that point. You cannot use arrow keys or mouse cursor to do anything in the tender window. I have found that occasionally the Escape key on the keyboard will allow you to close the tender window and then proceed with the transaction. Sometimes that doesn't work, and I have to actually log off the current Windows user and then log back in to get RMS to work again. There are no error messages that I can see when this happens.
This is not happening at any of our locations using WinXP 32-bit, so my hunch is that it has something to do with Win7 64 and the Mercury Pay/Retail Realm software. Has anybody seen this behavior or have any ideas?
