[1.0.1] IDE: want support for some global image repo

[RaiMan]

Using Sikuli 1.0.1.
Actually I have 2 questions but they related with each other :)
1) I want to save all scripts images in one directory. So, I'm trying to use the setting "use global Repository ".
There are following steps :
- set flag "use global Repository "
- set the path to directory "C:\SikuliX\image"
- save changes
- press "apply" button
- press "ok" button
- close Sikuli IDE
- start Sikuli IDE
- create a new script and take screenshot
- save script
The image was saved in the directory JYTHON_HOME\[script name].sikuli\image_name.png. So, I suppose it should be saved in another directory "C:\SikuliX\image".
Could you please explain me what i'm doing wrong.

2) I'm also tried to use SIKULI_IMAGE_PATH to find images which are not in [script name].sikuli directory. When I run a script it works fine but when i try to open pattern settings an error occurs and i can't edit it in SIkuli IDE :

Exception in thread "MainThread" java.lang.IllegalArgumentException: image == null!
