Hi Gus,
I am unable to reproduce what you describe in 6.3.7a of Visual WebGUI.
A code on a button's click handler that looks something like this:
PictureBox2.Width += 10
PictureBox2.Height += 10
Works quite nicely.
If you still can't make this work, then the best way to describe those problems is by creating a most minimal application that demonstrates the problem(s) and then send your application to support [at] visualwebgui [dot] com with a link to this forum thread, along with some description about how to reproduce the problem.
Please also clean the solution before compressing it and reply to this post after sending, so we will know to check for your support request.
