I have been running successfully Gansham's code given in test.py in the email thread "adding background image" started by me on 22 July. Wit the Win7 64-bit build of 2013-07-25 17:08 I suddenly get an error at the line
... File "", line 212, in addImage (line given above) File "C:\Program Files\McIDAS-V-System\idv.jar\ucar\unidata\idv\resources\python\shell.py", line 101, in makeDataSource NameError: global name 'idv' is not defined
I have used the same file as before when it worked.
