CAT Losing Ports

Options
I'm running SmartSDR CAT 3.3.32. I started up SmartSDR and WSJTx this morning and wasn't able to transmit. I check DAX and it was functioning correctly. After scratching my head a bit, I looked at CAT and discovered it had lost the PTT port. According to WSJTx Settings, it should have been serial port 12. I checked the Windows Device list and port 12 existed. When I tried to add PTT back using serial port 12, it wasn't available in the "Existing" drop down list. I had to create a new serial port (14) for PTT, then I could transmit. I deleted serial port 12 to avoid future confusion. Is it normal for SmartSDR CAT to lose it's marbles???

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
