# If you are using BWidget 1.7.0, please run following code.
# You will see a shaking ScrolledWindow. 
# The memory consumption keep increasing too.
# If change "-auto both" to "-auto none", no such behavior.
# wish8.3 does not had this problem. wish8.4 has it.
# Note, 1. replaced $bwidget_path to you BWidget directory.
#       2. "CP: 555  * AAA-I am shaking wildly 10mm dia:  59.5 mm" is  
#          a single line, Changing the length of the text dismantles the
#          shaking.
#       3. Shaking is caused by the appearing and disappearing of the scrollers
#          changing "-auto both" to "-auto vertical" dismantles the shaking.
# Any clue to solve it? Thanks.
# Environment:
#     Linux 2.4.21-9.ELsmp 
#     tcl/tk 8.4
#     BWidget 1.7.0
