Multicol package - right to left alignment?

[Barak Sh]

Hello,
I'm trying to use the multicol package in order to print a formula sheet
with 3 columns and a vertical line separating them. The document is in
Hebrew and should be aligned right to left.
When using the usual "Two-column document" setting in LyX, the columns are
aligned right to left as required. However, when using multicol, the columns
are aligned left to right.
Is there any way to solve this problem?
Thanks in advance,
Barak
