It is hard to tell what is going on because you aren't showing the actual Crystal Report so that we can identify sections. You might want to try placing the crosstabs in their own sections, and make sure the sections and the crosstab are formatted to "keep together".
You might also want to check the "relative positions" box for the section containing the crosstab, so that as one resizes, the other is not overlapped.
If you are saying that some data is not visible to the right, it suggests you are creating the crosstab in a subreport. There is a technique to fix this. Another alternative is to insert a group on a subset of the column field instances so that the number of columns in limited, and then place the crosstab in this new group section. But this means row summaries are limited to the smaller group of columns.
I think you need to explain more for additional help.
