After running any scene in the trial version, and stopping it with the editor stop button Unity.exe freezes. Killing the process with Task Manager does not help, because further Unity start attempts also freezed in the splash screen phaze. Both 1.0.3 and 1.0.4 produces this error.

This is only for (latest) Unity version 4.2.1. Pro
***edit ***
Correction: Unity 4.1.5 freezes too
*** end edit

- Windows 7 64bit
- Unity 4.2.1
- NoesisGUI 1.0.4 (latest, just downloading from this forum link NoesisGUI-1.0.4.4512-TrialEditor.unitypackage)

Can anyone reproduce this?

Thanks in advance

Thanks.

Really, killing adb.exe before hitting the Unity Editor stop button helps.
(why running a Windows platform build in Editor starts the Android debugger? And how it could lock the editor? ... mystery)

Yes, a mistery... we don't know yet how to solve this because we think it is Unity fault. For now, the only aggressive solution we have in mind is detecting the process and killing it... but that could generate side effects.
