Panels get permanently checked in 'Window' but aren't visible

[melek]

Describe the bug
When creating tabbed panels followed by using 'Restore Layout', panels can become inaccessible. Affected panels appear 'Checked' in the Window menu but aren't 'uncheckable' nor are open.

MapTool must then be restarted to regain access to the stuck panels.

To Reproduce
Steps to reproduce the behavior:

1. Select 'Restore Layout' from the Window menu to get to a common starting place.
2. Open the 'Connections' panel from the Window menu.
3. Open the 'Initiative' panel from the Window menu.
4. Drag the 'Initiative' panel onto the 'Connections' panel so as to add it as a tab to the pane.
5. Select 'Restore Layout' from the Window menu.
6. Open the 'Connections' panel from the Window menu.
7. Open the 'Window' menu. Observe that the 'Initiative' menu item is now checked, but is neither visible as a tab on the 'Connections' panel nor un-checkable.
8. If desired, continue tabbing non-default panels and restoring the layout to repeat the error until no non-default panels are accessible.
9. Restart MapTool to restore functionality.

Expected behavior
Tabbing panels then restoring the layout should not risk the user losing access to panels.

MapTool Info

• Version: 1.5.7rc-1
• Install: Upgrade from 1.5.6

Desktop (please complete the following information):

• OS: Windows
• Version 10

Additional context
I think that the Restore Layout function is intended to both reset the default panels size and positions as well as reset how the other panels will show up when opened, but during this test I sometimes had panels popping up as 'floated' after closing them that way and restoring the layout.

Some of those issues may be bugs from the JIDE framework.

Do we have the JIDE Free License for Open Source Project? If so we could try upgrading the JIDE famework from 3.2.3 to 3.7.8 and see if that fixes it.

[Phergus]

Yes. RPTools has a license for the JIDE libs. I know that @Azhrei had made an attempt to get the updated libs in the past without success but I don't know the details.

[Merudo]

The bug is also in 1.5.0, could be in 1.4.x too.

Is it okay if I contact the JIDE team and try to get the newest version?

[Phergus]

This bug has been there since way back. Probably 1.3 or earlier but definitely in 1.4.0.5.

Go ahead and reach out to them. Pretty sure the license for RPTools is under Trevor Croft's name.

[Azhrei]

I think the email address they have is probably admin@rptools (you know the domain name).

[Merudo]

PR #1028 fixes the inaccessibility problem.

[Phergus]

Tested. Working as expected.
