>>5231150If you're fretting over getting another pen art shouldn't been something you wanted to do as a career. At least with digital pens you can get another one for everything unlike markers or paints and have to find out that you ordered the right color but the new ones are a different shade entirely.
>>5231306My understanding of electronics is that water conducts electricity and bypasses the resisters in the hardware therefore pushing or drawing too much power and overloading or shorting the pieces. A huge lag delay means there is likely water still left in the pen, best not to use it until it is thoroughly dry and going into the tablet settings to see if calibrating will get rid of some of the delay. There should also be some brush settings within the drawing program that can help with jaggedness caused by the delay.
If none of that works best to just cough up the $ and get another pen, if you cant learn to use the mouse.
