cannot select from toolbar submenus on iPad

Hi, I'm playing around with MarvinJS on an iPad. I have found two problems with touch activation of the toolbars.

1. For toolbar buttons with submenus (bond, arrow, electron-flow arrow, and rectangle/ellipse), is very difficult to find just the right spot on the lower right corner of the toolbar button to press and hold so that the submenus will appear.


2. Even when I can get the submenus to appear, I am unable to select any of the options. For example, I cannot select the bold bond or the two-electron electron-flow arrow. Dragging my finger over to the desired option has no effect, and the submenus simply disappear when I lift my finger.

I thought MarvinJS was supposed to work on touch devices?

Hi Bob,

Which version of Marvin JS do you test on which version of ipad?

I suggest to use the latest version, we have fixed some bugs in the last release related to ipad.

I am asking your ipad info, because we test Marvin JS on iPad A1458 (4th generation) Safari 7.1.2

It's 4th generation (model A1458) running iOS 8.1. We are currently using MarvinJS 14.10.20. I'll upgrade MarvinJS to a more recent version and see if that helps. Thanks.

Upgrading to MarvinJS 14.11.10 hasn't helped. I have an easier time (press and hold) bringing up the submenu buttons, but I still cannot select any of the submenu buttons, either by dragging my finger over the buttons (no highlighting occurs) or by releasing and pressing an option (menu goes away when I release). This problem exists only using touch on my iPad; on my desktop computer with a mouse, I have no problems.

Thank you very much for the feedback. We are investigating this issue.

Regards, 
Eszter
