Default TETRA Demodulator Plug-in Errors

Is anyone else seeing the following two errors popup using this plug-in. (Released 5th June 2018)

I notice each one of the errors listed, appear at different times.
They only seem to appear when you have the "Network Info" window open for a few hours.

Clicking 'Continue' in the error popup seems to continue on with no apparent ill affect.

I tried joining the forum where the plug-in is posted, but I've not received approval to be able to report it.

The popup window is labeled "Microsoft .NET Framework"

Ian - I've been running this latest release for the past two+ hours, but not seen any errors yet. Will keep monitoring.

Hi, can you confirm that you are also running it with the 'Network Info' window open all the time.

Hi Ian.....yes, to confirm, have run it overnight on a busy set of carriers (albeit encrypted: you'll guess the network). No issues seen. I've tried a mix of running the Net Info window on top button enabled/disabled. I also spot that the GSSI/ISSI info has returned for Enc networks in this build.
Feel free to PM me if you want to exchange specifics. Jim

Thanks for the update.

I have tested with:
Windows 7 Professional 32 bit (shown errors)
Windows 7 Ultimate 64 bit (no errors), yet someone I know has reported seeing it on this version.

Not sure what the trigger is. I've been working on a program to use with this SDR# plug-in and originally thought it was the cause, but it does it even when my program is not running.

I think once the error occurs and is cleared, it doesn't reappear.

BTW: I think your mixing me up with "IanWraith" user.

Hi - sorry for the ID mix up.

I'm running on Win10 Home Build 1803, 64-bit still without error. Note I am not (yet) running your Trunk Tracker program.

OK good to know your OS, My problem maybe a 32 bit issue or just something in my setup.
I think I cheat and make a utility to close it when it sees it.

I'm eager to see if my TETRA Trunk Tracker program works elsewhere for people.
