Hello Statalisters,

I am experiencing a problem with how the strings are handled in the
dialogs (Stata 9). The attached code makes the problem apparent.

To reproduce the problem:

1. save the file into test_combo.dlg
2. db test_combo
3. When any item is selected, its name appears in the Stata results window
4. When "Other" is selected, a message will pop-up "We are OK"
5. Now replace "Other" with "Other...". Notice that it must be changed 2 times.
6. discard
7. db test_combo
8. When any item is selected, its name appears in the Stata results window
9. When "Other" is selected,  the message DOES NOT pop-up.

The problem relates to using points in the values. I want to notify a
user that a new dialog window will open if a particular value is
selected among the choices (which is conventionally done by placing
"..." after it).

Is there any quick fix to it?

Best regards,
    Sergiy Radyakin
