Microsoft Edge as a browser - recent problem with exchange betting?

This browser  now seems to intermittently pop out a drop down list when i'm trying to place bets fast in running - and aty other times but it's 'in running' when speed is of the essence and you do not want to be bothered with a 2-3 second delay while u get rid of the list and re-apply your bet.  Really annoying and cost me quite a few bets today and this past week.
Does any one else have this issue or is it just me??
