CTD on no write access

[Spu00Key]

When scanning / adding a bridge, it gets to the part to save the information, it will throw an exception on close if it does not have write access.

My Documents is under Ransom Protection. When it threw the exception Bit Defender notified me it blah blah blah. Added WinHue to the trusted apps. No issue next time.

Other than a graceful (write access denied) message, not sure there is anything else to do.

Noted I will add a message.

[Hyrules]

This exception is caused by something else. There is already a catch inside the function that saves the file. The messageadded event for some reason is not associated so I cannot trigger the event. I will have to review the whole application startup sequence.

[Hyrules]

if you want to try the beta in issue #46 I have moved the save file to the %AppData%\roaming folder so you might not have that problem anymore. Otherwise I will add a function to select where to save the file.

[Hyrules]

This should be fixed in the next version. I will release a new version soon.
