ttk::combobox .c -text btn
ttk::entry .e # either ttk::entry or entry

tk_getOpenFile # either this or tk_getSaveFile

~ Steps to Reproduce

0. Save the code above as a script file
1. Run it
2. Deal with the "Open File" stuff. Try to click on the entry; nothing happens
3. Click on combobox's button
4. Then click on the entry; it gets the focus

~ Actual Results

The entry can't get the focus before we click on the combobox

~ Expected Results

The entry should always be responsible for user's clicks.

Windows 7 x64.

Adding [focus .e] doesn't help.
