After the SWFOX sessions, I have been using Craig Boyd's compression FLL and Alan Stevens suggestions on using to compress XML files. In testing so far, I attempted to put into a memo file a compressed XML. However on trying to get the cursor back after compression I kept getting the following error.

"XML Parse error: An invalid character was found in text content."

So instead of a memo field, it made it a Blob field and was successful in getting the cursor back with out errors.

My question is, why does this seem to work and secondly is there any possible issues that I am not thinking of by using the Blob field?

(by using the Blob field, I am able to compress 28MB of data down to 2MB. I was real excited when using the memo field i was able to compress down to 4kb, but could not extract.)
