Thanks in Advance,
Pavan.

Do you have any when-new-form/block/record/item-instance triggers that might be firing in the process?
Or other triggers?
I doubt the problem is just displaying the canvas.

Is this the first form being called or is it being called from another form?
Are you using jinitiator or JRE?
Are you using an application server or running Forms Developer?

the form is being called by another form i.e Main menu form calls form A. in when-new-form-instance of Form-A calls another Form-B this inturns calls Form-C. after entering Form-C it goes to Form-B and then to Form-A. so here when comes to Form-A i'm showing a content canvas (balnk) and on top of this showing a stacked canvas to display list of choices.

Form-A is a big size nearly 6 MB.

using Jinitiator. and using Oracle Applicaiton server. Please help me how can i reduce the time to load the canvas.

Does this "big form" perform some kind of EXECUTE_QUERY? If so, how many records does it fetch? Can you restrict that number (see data block Property Palette window; see "Query all records", "Maximum records fetched" properties).

You didn't answer Cookiemonster's questions (about possible triggers firing and slowing things down).

the "big form" is a data entry screen, it does not perform execute_query.

with regard to Cookiemonster's questions => the "big form" has triggers, they are
pre-form => in this trigger global variable settings and flexi label settings are done.
when-new-form-instance => in this trigger it does some user security validations, calls form-B and finally go_block('Choice') which takes to the choice field of the stacked canvas (display choices like SALE, Return etc).
when-new-item-instance => start of the trigger it shows the content canvas, the choice field belongs to the stacked canvas.

and one more thing, for each screen we are attaching a horizontal tool bar (canvas) where displaying buttons with images (example, next field, previous field, exit) depending on the screen type (entry, query, find or detail).
