A Meridian departed en route to LBF. There was a line of severe precipitation extending from HYS to the Northeast. ZMP is running ERAM. The Meridian asked about the line of weather; and I told him the line extended to around HYS. He advised that they would deviate to there and then turn to LBF; and I cleared him to do that. I tried a track pick reroute; using a point south of HYS; and then direct LBF; but I was unable to complete the entry. After several attempts; I realized the pick part of the entry wasn't working. I instead made the entry by entering a HYS radial and DME fix instead; and called for an ERAM Subject Matter Expert (SME). He began documenting the problem. According to one of our ERAM cadre; this was a known problem. Apparently the trackball pick functionality doesn't work in that area. He told the SME that he didn't need to write up the bug as it was already a known issue. However; I was under the impression that we were supposed to be documenting all bugs we experienced in ERAM. Dealing with this bug and helping document it was a big distraction to me. Also; it's another case where there was a known bug that controllers weren't advised of. ERAM bugs need to be fixed; and controllers need to be briefed on all known bugs.
ZMP Controller voiced concerns regarding the functionality of ERAM equipment.
