Hey guys, I have been experiencing freeze ups (no matter how long I wait) when starting or stopping communications with a PLC. The only solution I can come up with is to open task manager and manually terminate the DoMore Designer application AND the PLC Communications Server Application. Only then can I restart the program and connect. This happens pretty consistently. Sometimes the first time connecting to a PLC and no less than the fourth or fifth time connecting. I have observed the following :
- It Only happens during the connecting to, disconnecting from, or write to PLC Command
- Happens across multiple PC's although all are running windows 11
- Have to open task manager and kill DoMore Designer AND PLC Communications server 32
- Only happened after updating to 2.11.1 from 2.10.*
Any suggestions?

I know we have seen some issues when adding a "new device" to your PC. When Windows sends a message that a "new device" has shown up (it can be a PRINTER or a USB drive, not just something related to a PLC), Designer attempts to resolve that device, and sometimes it "hangs" :P
I had fixed some old code for 2.11 that apparently does not work properly. I have addressed that and we are looking to ship a 2.11.2 soon.
In the meantime, I recommend that you power up any USB bench PLCs or USB to Ethernet or VPN connections, or connect any USB drivers or printers BEFORE launching Designer. So sorry.

Although I am not adding or removing devices, that is not to say that you are not on the right track. Once I start designer, then connect to the PLC, (or sometimes I just try to connect) and the program can hang on connect, during download, or even after disconnect. Its rarely inbetween.

There were issues dealing with "modality" and "z-order" of status windows/message boxes when connecting to a PLC or writing a project to the PLC.
Are your PLC network connections typically all good? We do see strangeness when dealing with "not-so-good" connections via VPNs (lots of layers and hops that aren't the best).
