Grid lines (portable 2009.2a) sometimes out of alignment

[troppo]

I find the spreadsheet-style grid lines useful (especially after a long day) but sometimes these go out of horizontal alignment with the files. Haven't got an image - will try to capture next time it happens. Corrects itself after a while, but sometimes results in multiple incorrect file selection when it is happening. [Win XP Home SP3, AMD Sempron, 2.21Ghz 3.37Gb].
(Great program - Norton Commander user since 1986 but NC no longer reliable.)
