I wonder if you create a custom Resource.xml file with that key explicitly disabled that it may override the internal handling.
https://wiki.jriver.com/index.php/User_Defined_Global_Keyboard_Shortcuts
1. Create a new file: C:\Program Files\J River\Media Center 23\Data\Custom Resources\Resource.xml
2. Add this to it:
<MJRS version="1.0">
<ACCELERATORS>
<Entry Key="Space" Command="10000" Param="0" Global="0" />
</ACCELERATORS>
</MJRS>
3. Save and restart MC.
I have tried that prior to your suggestion but it does not work I wonder why. It doesn't disable the space key.
I also tried to change the space key to stop instead of pause/play like this:
<MJRS version="1.0">
<ACCELERATORS>
<Entry Key="Space" Command="10002" Param="0" Global="0" />
</ACCELERATORS>
</MJRS>
But it did not change the default behavior of the space key into stop instead of pause/play, it just ignores what is inside the Custom Resources folder.
Maybe it is hard coded into the system. Are you sure that this is the right way to disable it?
I wonder why am I the only one that has noticed this problem? Are all of you use different settings than mine?
I would be happy if one of the JRiver staff will give his observation regarding this issue.
Thanks
