Changed behavior so as not to indicate the error message box when DynamicVariables is 1 and FontSize is 0. (issue 126)

FIXED: Virtual Bytes usage for an x64 process with perfmon plugin does not display value greater than 4 GB (issue 113)
The numerical value greater than 32bit can be now displayed when NumOfDecimals is 0 in Meter=STRING.
Fixed the broken compatibility in Windows 2000. (AboutDialog, SysInfo)
