[1.0.1 ok] IDE: Windows: imported images not found on 2nd script run

----- fixed with version 1.0.1 per September 12 at 3 pm gmt+1
repeat setup after this time to get the fixed version
----------------------------------------------------------

im trying to run a script which depends on images stored in an imported .sikuli. the first time i run the script from the ide it works as expected. the second time i get the following error message:

[error] 1372711263469.png looks like a file, but not on disk. Assume it's text.

[error] script [ Bscript ] stopped with error in line 4
[error] FindFailed ( can not find 1372711263469.png on the screen. )

here is the script that fails:

from sikuli import *
import oxpTools as oxp
Settings.MoveMouseDelay = 0.01
billingQueue = oxp.OxpQueue(queue='Billing')
billingQueue.filterQueue(status='25',payorType='1')

any ideas?
