X-1.0rc3: IDE: will not start anymore on XP SP3 --- workaround

[ubs]

**** workaround

see faq 1766

Removing HKEY_CURRENT_USER\Software\JavaSoft\Prefs\org\sikuli\ide fixed the problem.

----------------------------------------------------------

Summary:
Sikilu RC3 used to work on this machine for the past two weeks. This morning it decided to stop working. IDE will not display or start up. What is weird is I can still run my executable script I made before the IDE stopped working.

Java Installed: JRE6 Update 27
OS: Windows XP SP3 with latest updates

Attempted Work Arounds:
I have uninstalled JRE and Sikuli then re installed back on, which did not work.
I have tried running the batch files directly instead of the exe or exe short cut which did not work.
I have even tried newer JRE6 with Update 29 which did not work
I have tried editing the bat file t include the language switch as I have seen in another bug which did not work.
I have tried portable versions of Sikuli which did not work.

try to reset the registry container where Sikuli stores the information to restore the situation of the last session (you might have moved or deleted a .sikuli that was opened in a tab, when you stopped the IDE the last time).

see faq 1766
