Thanks to you all for testing. This is what we found and fixed :)
In the meantime we noticed that me and my partners were closing excel differently. I always used Alt+F4 and they always used Ctrl+F4 first.
Interesting if sheet is closed first and no releasing of Excel, window is alive. You can see it on tasks list, and detect with iswindow (but not with FindWindow). Even show it up with oExcel.visible = .t. but closing sheet immediately closes whole excel from visible environment.
After struggling with API *Window I did old days solution :) The workaround I now use is :

myHandle = fopen(lcTempExcelFile,12)
do while myHandle < 0
  myHandle = fopen(lcTempExcelFile,12) && Try to open temp xls read-write
enddo
=fclose(myHandle) && Excel released it
Release oExcel
Erase (lcTempExcelFile)

This one is working error free on all sites now :) Thanks again.
