Calc Window will not open maximized

RE: LO v5.1.5.2 on Win7 Pro 64bit

LO Calc will NOT open maximized, even with link property set. I have to click max-button every time.

NOTE: LO Writer does NOT HAVE THIS PROBLEM. So it’s just Calc.

LO v5.1.4.2 did not have this problem.

The LO update v5.2.2 fixed the problem.
