running this code I get full cpu usage:

package require Tk

ttk::label .l0 -text "Details:" -anchor center
grid .l0 -sticky w

ttk::button .create -text {Create folder}
pack .create -side bottom -fill x

vwait forever

is this a bug?

This is a documented restriction. Only one type of geometry manager can be
used on a master ("." in this case) at a time.

You can, of course, use a different geometry managers on different masters.
The following is legal:
ttk::frame .f1
pack .f1 -side bottom
ttk::label .f1.l0 -text "Details:" -anchor center
grid .f1.l0 -sticky w

ttk::button .create -text {Create folder}
pack .create -side bottom -fill x


Note -- with wish no vwait is needed.

for me it looks like a bug. If there is a restriction then give an
error message. 100% cpu is not a user friendly message :-)

thanks for the tip with vwait. long time since I played with Tk and it
feels nice to be back.

You are right, and it is fixed in 8.6 HEAD.
