Business Logic Editor with Complex Transasctions

Question

I'm starting to have some serious problems using the Business Logic Editor with reasonably large (but by no means huge) transactions. These transactions also have nested transaction calls down a few layers. The main symptoms are:
1)  When opening the Link Editor on the first action it is somewhat sluggish. Opening the Link Editor on the last action can take over 60 seconds.
2)  If adding a new Transaction Call action, selecting the called transaction in the Configure window doesn't work. The transaction can be selected OK, but the browse window will not close. It has to be cancelled. The Link Editor does not show the transaction's input, even though the Configure window will now show the selected transaction's path OK.
3)  If the transaction is Saved after 2), that transaction will not open again in the Logic Editor, even after a reboot.
Memory seems to be part of the formula. The above is on a notebook with 1Gb of RAM. On a dual core with 2 Gb, the problems are less, but not much. On a server with 8Gb, the symptoms disappear.
Does anyone know if there is a recommended minimum system config for using the Logic Editor?
What is actually happening when a transaction with nested Transaction Call actions is loaded in the Editor and for exection? I have many transactions that don't have the above problems, but they take a long time to open in the Logic Editor, and up to 1.5 seconds to load when executing the transaction (this is as per the F5 timings).
Thanks,
Bill

Rick,
These days I'm very careful about large embedded reference docs in my transactions. I actually go through the .trx files with notebook looking for any large chunks of that sort of XML and make sure they are eliminated.
In the case of this transaction, by the time I get to the actual SQL query action (and remember it's a few layers of nested transaction calls down), it can't run the query anyway. The Query Template name in the configure window is blank. That and any params are set dynamically in Links at run time (the Query Template name actually comes from a config file). If I try Limit Rowcount or Yes when I close the configure window, it just gives an error because it has no idea what query template to run.
Given this, the problem just doesn't seem related to fetching data. And how would this cause the Links window to take so long to open in the Logic Editor?
