Any way to vary form appearance depending on reader program?

I've run into the reasonably-well-documented problem of people submitting my Acrobat-Pro-XI-created form and appearing to have written only a single line of text (when in fact, there is tons of text that will appear whn you click inside the field).

Adobe seem unbothered, but this is a real headache for us - we want to have a fillable job application form, but are having people return forms with some data invisible. Where we spot truncation, we can use the workaround (change field background to white), but what if the truncation in visible text isn't obvious? We'd have to apply the workaround to every field of every submitted form, and we don't have the time.

Some suggest that the problem is down to certain reader programs/versions. Already I have to have a socking great banner warning people not to fill in the form using a web browser (Chrome, for example, seems to let people fill in the form, but doesn't save the contents: handy!) If I knew exactly which reader programs and versions were going to cause problems, I could add a list - but that's hardly professional.

I am looking for an Acrobat equivalent of the "sniffer" code that many websites use - they establish which browser is being used, and then modify what they serve to suit the browser and version. Can one include code in a pdf created in Acrobat Pro so that is shows different text depending on whether the pdf is being viewed in Chrome rather than Acrobat Reader (for example)? That way, I might have a hope of warning people that they are filling in the form using inappropriate software. Without it, I fear that we will have to give up on pdf application forms altogether.
