address on envelpes

My computer,windows 98,office2000 Arabic enabled. Before enable Arabic, while I type address in English on envelopes, the address was aligned left as usual. but now after Arabic enabled, whenever i type address in English, it becomes right aligned. Even if i aligned the address by using space bar, when printing on envelope it becomes right aligned. how can i solve this?

English is left justified, Arabic right justified. For example note the writing on the right side of this screen http://www.iaf.org.il. Then click the first button on the left and note the justification on the paragraphs.
