cec-tray crashes with System.ObjectDisposedException with Kodi

[lukjak]

Hello,

cec-tray (6.0.2) crashes with exception when Kodi (https://kodi.tv) application starts. Please mind that I use my own Kodi build with all CEC support disabled and which does not load cec.dll - so there is no conflict here.

System.ObjectDisposedException
   w System.Windows.Forms.Control.CreateHandle()
   w System.Windows.Forms.Form.CreateHandle()
   w LibCECTray.ui.CECTray.SetVisibleCore(Boolean)
   w System.Windows.Forms.Control.Hide()

   w System.Threading.ExecutionContext.Run(System.Threading.ExecutionContext, System.Threading.ContextCallback, System.Object)
   w System.Threading.ThreadHelper.ThreadStart()

Background for this problem:

My current TV/Amp/PC setup is not working quite correctly with the current Kodi (20.1 libcec 4.0.4 or 4.0.7) - xbmc/xbmc#23260. I wanted to try to use cec-tray for controlling Kodi instead of built-in support, as it seems to always work correctly, but I observed that cec-tray is closed immediately upon Kodi startup. I thought it is some CEC clients collision. So I build a Kodi version totally without CEC support (it does not require cec.dll to run at all) and observed the same issue with cec-tray. Then I discovered the problem in Windows Event Log.
