winforms - Main form not shown in Taskbar -

-

what reasons main application form not shown in taskbar?

showintaskbar property set "true", form doesn't show there if after running application , before main form appears switch other window. form exists, until minimize apps above make visible, won't show in taskbar.

update. form not have owner.

i've added form.activate() after form.show(). jumps out when loaded, , doesn't lost under other screens.

though not solution, crutch, responses welcome anyway.
