File Sink stop recording after click on "settings" tab

[krzotr]

Hi,

I was tested on sdrangel-7.21.1-win64. I accidentally clicked on the "Settings" tab during recording - FIle Sink. It looks like this action means stop recording - finally my .sdriq file has 6 seconds instead of 16.

Steps to reproduce - You can also see the video:

• RemoteTCPInput - add channel File Sink
• click the button Open File and put test as a name
• click the button Start/Stop recording (the button now is red)
• after 6 seconds click Settings and click again
  • right top corner, timer reset, is 00:00:00
  • Start/Stop recording is still red
• click the button stop recording
• add RX Device - FileInput
• open test file
• the file is only 6 seconds and 12 MB, it should be 15 seconds

BTW, After adding FIle Sink I see a size of 999.99M - is annoying
