SLADE refuses to allow iwad_lock to be changed

[WoolieWool]

SLADE Version

ce9593a

OS

Linux

Editor

Resource editor

Steps to Reproduce and Observed Behavior

1. Edit IWAD file
2. Attempt to save IWAD file to another filename (I am trying to cut the UMAPINFO out of the Night Dive Heretic + Hexen remaster as it interferes with *ZDoom ports)
3. Get "IWAD saving is disabled" error dialog.
4. Go into advanced settings and attempt to edit iwad_lock, clicking on it does not open any text box
5. Edit ~/.slade3/slade3.cfg and change iwad_lock true to iwad_lock false
6. Reload SLADE. SLADE will immediately set iwad_lock true without asking.

Expected Behavior

SLADE should respect the user's wishes and not change its own configuration to something the user does not desire.

I'm not sure what's going on there, but there are meant to be checkboxes in the boolean cvar rows, maybe something weird is going on with your theme and the checkboxes are white?

Either way I can't reproduce this on Windows or Linux - changing iwad_lock to 0 keeps it as 0 between sessions
