I encountered this problem enabling WIN32_NATIVECTLS on combo-box
Combobox that expands upward
I select an item and ... combobox disappear.
When i push "tab" the combobox appears again.
The problem occurs on Windows Server 2008, Windows Server 2003, with runtime 9.0.1 e 9.1.2 (I didn't checked older runtime . . .)
I solved with workaround: after nft-selchange I mage the combo invisible and after visible.
inquire cbox-pag, value in w-combo-pag
move w-combo-pag(1:3) to w-codice-pag
perform leggo-pag thru leggo-pag-ex
perform ab-situazione thru ab-situazione-ex
modify cbox-pag, visible we-off
modify cbox-pag, visible we-on
It might be a runtime bug ?
