Michael Saunders | I recently had an issue where an update to Chrome broke my app (Running form my Android mobile phone) It occurs on the TButton's Onclick event There is no problem when a mouse click initiates this event from the desktop but when it is a touchscreen then I have had to change the code to set the buttons enabled property to False straight away before set ting it back to True only wnen all processing has completed If not then I get a duplicate key error message when adding a new record to the database It would appear the the event is firing for a second time no matter how quick I am with the finger tap
Note that there is no issue with Firefox and with previous Chrome releases So Is the Onclick event the correct event to activate a touchscreen button and if so is what I have done the best solution to fix it Also has anyone else experienced issues where browser changes have caused issues similar to this Do you block browser updates and if not how do you monitor what is is being changed It is of concern to me that I can be providing apps which work fine one day and fail the next due to changes beyond my control Next time I may not be able to fix it so easily What is the recommended approach here Many thanks in advance |

Uli Becker | Michael,
I remember there was a bug firing clicks twice on mobile devices. I suggest to use the latest version of EWB where that has been fixed. No "workaround" should be needed for simple clicks. Uli |

In general, it's *very* rare for a regression in something so fundamental to crop up in Chrome. Most of the time, it's probably a bug in EWB. Tim Young Elevate Software www.elevatesoft.com |
