Install Error

Hello:


I always encounter error:install error.


This happens mostly when multi windows using Marvin space are opened.


Does jogl affects this?

I test MarvinSpace+4.1.10 yesterday, and rocover to 4.1.8,


but temprory files in C:\Documents and Settings\liuhai\chemaxon\lib\jogl_1.1.0-rc2 already exist.





when visit the same pages but using another version Marvin, class loader may get an exception.

Hello,





this is a Java security issue that rises because MarvinSpace uses OpenGL natives.


Java does not let to use one native library (dll in this case) by multiple programs.





Though if started by the same classloader, the applet can be used arbitrary times.


This requires exactly the same "applet tag" to be used. It is briefly desrcibed at the end of this example.





If this happens, the browser should be restarted to let it work again.


Yes, using separate versions without restarting the browser also cause this.
