Perhaps start afresh.

i deleted the android sdk. java jdk. everything related to processing and reinstallrd just processing three times and also tried reinstalling processing and javas jdk a few times. nothing seems to work. deleted preferences twice as well. tried renaming fokders but processing just generates them when you go toturn it on or run it. not sure what else to do

Do you have this problem with all kinds of sketches (using the default renderer)? Your OpenGL driver can be a problem with old computers, but default is pure Java2D, so should work.

this laptop i never installed any libraries. just android mode originally.but i will see if the gfx has been updated at all. it hasnt even been turned on in the past 5 yrs. so maybe that could do the trick.

I been experiencing a similar problem for 2 days now and it is driving me nuts as well.

Processing launches (slowly - at least slower than before) but when I attempt to run a sketch (Java mode using the JAVA2D renderer) the display window takes several minutes to appear even though the java.exe process appears in Task Manager immediately.

I have tried

1. updating graphics drivers
2. re-installing latest Java
   
3. re-installing Processing (32 & 64 bit versions)
4. using a new Processing folder (so no contributed libraries and tools)
5. enabled Processing's copy of java.exe access through my firewall

The worst of it is that after running a sketch and closing it and Processing down my computer is extremely unresponsive regarding using other applications e.g. Firefox. I have to reboot ny computer for it to become usable.

My OS is Windows 7 64 bit

Is anyone else having a similar problem? If so did you find the solution?

UPDATE
I have tried Processing 2.0(64), 2.0.1(32 & 64) and 2.0.2(64) all with hthe same result.

I posted a but report on github on this issue a while back, you can review suggestions for fixes from the dev team here:

Thanks for that.

Just to let you know I have added my own problem to the issue report.
