вызовы функций из syslevel - это следствие вызовов mutex'ов (критических 
секций).
При вызове меню Поиск по источнику опубликования или Поиск по ситуации Гарант 
работает стабильно. Отмечу, что при этом не происходит попытки чтения файла 
E:\\Garant\\apps\\f1shell.run-up1.txt.

NtCreateFile возвращает status=c00000a2, ни в одном предыдущем случае такого не 
было. Обычно возвращает c0000034.
