Last Delete in ESI text box not registered

[jd13]

Hi

I have a text box in the EIS used as parameter passed to a query. The problem is that when the value of the text box is changed the, if the last keystroke is the delete key, the change is not recorded when reading the value in a script.

Example :

text box value is "abcd"
enter the field and use the delete key leave the value "cd"
use a script to display the value of the textbox Alert(txtBox.Text) and the value shown is "bcd"

Is there any way to force the last delet keystoke to be recognised?

Thanks
James
