no popup of uncompiled request fields

hallo,

i have a error when in front end when a user don't compile a request field.

all browsers show a popup whith "xxxx field is request". this is correct.

at the same, explorer don't show this window. than the submit can't terminate and the user haven't the name of field where insert the data.

where is the problem? .... or there is a solution?

thanks
