Re: screenshots note

[m . gallucci]

I thank very much who answered. I understand the problem, but since it
works with KDE, that's fine with me. For dubugging reasons, I specify
what I mean for "does not work"


With enlightenment, the program produces the first screenshot (at time
1), then it crashes when producing the second screenshot, with the
following message:
"
  X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  73 (X_GetImage)
  Serial number of failed request:  15323
  Current serial number in output stream:  15323
"
The code I use is the standard code [[[[[Pixmap creatBeing....]]]drop],
found in Heatbug.

My message was intended to mean something like "if someone is in an
hurry and screen shooting does not work, try KDE".

Cheers
marcello
