Hi,
it seems I have a similar problem – here is the fix I use:
Problem: When using QSM on an screen with a small width (e.g. a Smartphone) a css defines for “.qmn_pagination” (in which the submit-button is embedded) a max-height of 50px. This led in im my case to showing only about half of the submit button.
Fix: I use the style “gray” with loads the css “qmn_gray.css”. In this css-file I replaced in the definiton of “.qmn_pagination” the line “max-height: 50px” with “max-height: initial”
Perhaps the creators of qsm could look into this issue?
best,
Ralph
