Hi Rose,

try your test program again and change line 8 to the following:

axes = CW_FSLIDER(base,VALUE=0.0, $
MAXIMUM=300.0, MINIMUM=-300.0, /EDIT,FRAME=5)

The effect is, that the current value is set to -300.
If, however, you change line 8 to

axes = CW_FSLIDER(base,VALUE=53.1, $
MAXIMUM=300.0, MINIMUM=-300.0, /EDIT,FRAME=5)

it works fine as it should.

By the way, I am sorry for posting the last message in HTML - thank you for your
e-mails.

Heiko
